New York Water Quality at a Glance
Is New York Water Safe to Drink?
Highly Variable Quality Across the State. NYC enjoys some of the world’s best tap water from protected upstate watersheds, but other regions face serious challenges. Over 1.25 million service lines statewide are lead or possibly lead, potentially affecting 3.1 million New Yorkers. About 250 public water systems exceed the state’s own PFAS standards of 10 ppt. Rural soils show PFOS detected in more than 97% of samples statewide. Governor Hochul’s 2026 State of the State proposed an additional $3.75 billion for water and sewer infrastructure, bringing total state investment since 2017 to nearly $10 billion.
⚠️ Key Concerns for New York Residents — 2026
- Lead Pipes Crisis: More than 1.25 million service lines in New York are lead or possibly lead — over one in three — potentially affecting 3.1 million residents (NY League of Conservation Voters, Nov 2025). NYC alone has 123,000 pipes in need of replacement. Federal rules now require most systems to replace all lead lines within 10 years of 2027.
- Statewide PFAS: ~250 systems exceed New York’s own PFAS standards of 10 ppt for PFOA/PFOS. DEC’s December 2025 rural soil study found PFOS in more than 97% of statewide surface soil samples — confirming PFAS is ubiquitous, not confined to industrial sites.
- Long Island: Heavily impacted by legacy PFAS from industrial sources and airports, plus nitrogen pollution from approximately 380,000 septic systems threatening groundwater used by millions of residents.
- Private Wells: Approximately 1 million private wells in New York are unregulated. A new 2026 pilot programme offers free PFAS testing and up to $10,000 in rebates for well owners in six counties, including Suffolk and Westchester.

New York — The Empire State — Water Quality Report 2026: PFAS Testing, Lead Pipes & Safety Across Your State
New York’s water infrastructure serves approximately 19.5 million residents across diverse geographical regions, from the Adirondack Mountains in the north to Long Island Sound in the south. The state operates through a complex network of over 9,000 public water systems, ranging from New York City’s massive unfiltered system serving 8.3 million customers to smaller rural systems providing essential services to underserved communities. New York’s water sources include the Great Lakes, Hudson River, Finger Lakes, and numerous reservoirs and groundwater aquifers that supply both urban centres and agricultural areas.
New York faces significant and growing infrastructure challenges. More than one in three service lines statewide — over 1.25 million pipes — are lead or possibly lead, potentially affecting 3.1 million New Yorkers, according to a November 2025 analysis by the NY League of Conservation Voters. On PFAS, DEC’s December 2025 rural soil study found PFOS detected in more than 97% of statewide surface soil samples, confirming that contamination is far broader than previously understood. Governor Hochul’s 2026 State of the State proposed an additional $3.75 billion in water and sewer investment, bringing total state funding since 2017 to nearly $10 billion. New York remains a national leader in PFAS regulation, having set its own enforceable drinking water standards of 10 ppt for PFOA and PFOS in 2020, and continues to expand product bans and monitoring requirements in 2026.
New York Water Quality: Current Status (2025–2026)
Statewide Compliance and Testing
- Overall Compliance: Nearly 95% of New York’s public water systems meet federal Safe Drinking Water Act standards. However, approximately 250 systems exceed the state’s own PFAS standards of 10 ppt for PFOA and PFOS, and about 189 systems have detected PFAS between 4–10 ppt that will require action under federal limits (MCL compliance extended to 2031 by EPA). Use our water quality checker to look up your local system.
- PFAS — Bigger Than Previously Known: DEC’s December 2025 rural soil background study confirmed PFOS detected in more than 97% of statewide surface soil samples and PFOA in 76.5% — including in areas with no known industrial sources. DEC Commissioner Amanda Lefton has stated: “These contaminants are no longer emerging but are here for the long run.” In early 2026, DEC held a virtual public meeting series to address new PFAS policies, landfill leachate regulations, and biosolid sampling programmes.
- Record Infrastructure Investment: Governor Hochul’s FY26 Budget allocated $500 million in clean water infrastructure, bringing total state investment since 2017 to $6 billion. The 2026 State of the State proposed a further $3.75 billion, which would bring the cumulative total to nearly $10 billion. This includes $66 million specifically for lead service line replacement and $3.4 billion in financial assistance from the Environmental Facilities Corporation for local water projects in FY2025 alone.

Lead Service Lines — A Growing Emergency
- Scale of the Problem: More than 1.25 million — over one in three — New York State service lines are either made of lead or of unknown material, potentially affecting 3.1 million residents (NY League of Conservation Voters, November 2025). New York City alone has 123,000 pipes in need of replacement. On Long Island, over 90% of Nassau County’s lead pipes are concentrated in just eight water districts.
- Federal Action Deadline: The EPA’s updated Lead and Copper Rule Improvements require the vast majority of water systems to replace all lead service lines within 10 years of 2027. New York school lead testing requirements are also changing in 2026, with updated sampling and reporting rules for all public schools and charter schools (action threshold: 5 µg/L).
- NYC Lead Risk: While NYC’s source water is lead-free, more than one-third of home test kits submitted over the past decade showed some lead contamination (The City, August 2025). Nearly half a million residential units in NYC are supplied by lead pipes; another 403,000 are served by lines not yet confirmed lead-free. Residents in pre-1961 buildings are at highest risk. See our New York City water quality page for detailed guidance.
Major Water Sources and Challenges
- New York City System: The largest unfiltered water system in the US serves 8.3 million customers from upstate Catskill/Delaware and Croton reservoirs. Source water PFAS levels are among the lowest of any major US city — well below both state (10 ppt) and federal (4 ppt) limits — but lead from building plumbing remains a concern in older properties.
- Long Island Aquifers: Heavily impacted by legacy PFAS contamination from industrial sources and airports, plus nitrogen pollution from approximately 380,000 septic systems. Over 600,000 Long Island residents are exposed to PFAS above EPA standards. Extensive treatment and monitoring is required to protect groundwater that millions of residents depend on.
- Aging Infrastructure: With some distribution systems over 100 years old, New York faces a $44.2 billion need for drinking water infrastructure improvements over the next 20 years. As of August 2025, 140 public water systems (5%) had still not submitted required lead service line inventory data to DOH.
PFAS Regulation and Legislative Response — 2026
- Private Well PFAS Pilot Programme: Launched in 2026, New York’s Private Well PFAS Testing and Mitigation Rebate Pilot Programme offers free PFAS testing for well owners in Dutchess, Putnam, Orange, Suffolk, Ulster, and Westchester Counties. If PFOA or PFOS levels exceed 10 ppt, residents can claim up to $5,000 for a home treatment system or up to $10,000 to connect to public water. There are approximately 1 million private wells in New York. See our water filter solutions guide for PFAS-certified options.
- New Product Bans: New York passed legislation in early 2026 prohibiting the sale of PFAS-contaminated household products and menstrual products. Carpet PFAS bans take effect December 31, 2026. Outdoor apparel bans follow in 2028. In 2026, DEC is also proposing implementing regulations for PFAS in apparel following the 2025 law. The NY Senate passed a broader 2026 bill to prohibit PFAS in consumer goods, with the Citizens Campaign for the Environment calling it essential while the federal government steps back from environmental enforcement.
- Landfill Leachate Regulations: Governor Hochul’s 2026 State of the State directed DEC to develop draft regulations requiring landfills to treat leachate — which can contain high concentrations of PFAS — at the source before discharge to wastewater treatment plants. This addresses a key contamination pathway not previously regulated. Public information sessions were held in January and February 2026.
- State PFAS Standards: New York was among the first states to set enforceable PFAS drinking water MCLs in 2020 (10 ppt for PFOA/PFOS; 1 ppb for 1,4-dioxane). The state is now working to pass standards for up to 23 additional PFAS compounds and to harmonise with the new federal 4 ppt MCL by 2031. New York’s 10-year “Decade of Progress on PFAS” report was released in late 2025.
Rural and Disadvantaged Communities
- Infrastructure Disparities: Small and medium-sized communities face challenges accessing state funding, with complex application processes and upfront costs creating barriers to improvement. The state is implementing simplified grant processes as part of record investment commitments.
- Private Well Risks: Approximately 1 million New Yorkers rely on private wells that are not federally regulated. DEC and DOH have tested 5,000 wells over the past decade; the 2026 pilot programme expands this effort in the most vulnerable counties.
Looking Forward: 2026–2031
New York’s water quality landscape is undergoing significant transformation in 2026. The state’s early adoption of PFAS standards, combined with record investment levels and the December 2025 rural soil study revealing near-universal PFAS presence, has intensified regulatory action across all fronts — from landfill leachate to biosolids to wastewater treatment plant permitting. Successful implementation will require sustained investment exceeding $44 billion over 20 years to modernise aging infrastructure, replace lead service lines within the federal 10-year mandate, and ensure all New Yorkers — including rural well users — have access to safe, affordable drinking water. Residents should check their utility’s Consumer Confidence Report, look up lead pipe status for their address, and consider certified filtration if PFAS or lead is a concern. Follow our water alert news page for the latest New York water quality developments.
Recommendations for New York Residents
Know Your Water Source & Pipes
Request your utility’s Consumer Confidence Report and check whether your address has a lead service line using the NY League of Conservation Voters’ interactive map. If you live in a pre-1961 building, have your tap water tested for lead. Use our water quality checker to look up your local system’s reported contaminants. Private well owners in eligible counties can apply for free PFAS testing through the state’s 2026 pilot programme.
Support Infrastructure Investment
Stay informed about local water infrastructure needs and support utility rate structures that enable necessary improvements. Attend public hearings about PFAS treatment investments and lead pipe replacement plans. New York’s record $6 billion commitment since 2017 — with a further $3.75 billion proposed — depends on communities engaging with the process to ensure funding reaches those who need it most.
Consider Certified Filtration
For areas with known PFAS contamination — particularly on Long Island or near industrial sites — NSF-certified reverse osmosis or activated carbon filters are the most effective option. For lead concerns in older buildings, a certified point-of-use filter is the quickest protective measure while pipe replacement proceeds. See our water filter solutions guide for PFAS-rated and lead-rated options with FTC-compliant reviews.
Report Water Quality Concerns
Contact your local water utility immediately for taste, odour, or colour concerns. Report suspected contamination to the New York State Department of Health or DEC for investigation, especially if you’re on a private well. Track active alerts and boil water notices on our live US boil water notices tracker.
Stay Informed on Legislation
Follow New York’s expanding PFAS product bans — carpet bans take effect December 2026, outdoor apparel in 2028. Engage in public comment periods on DEC’s landfill leachate regulations and biosolids rules being developed in 2026. Follow our water alert news for the latest state and national drinking water developments.

Frequently Asked Questions
Is New York’s tap water safe to drink?
Nearly 95% of New York’s public water systems meet federal Safe Drinking Water Act standards and are generally safe for consumption. However, quality varies significantly by region and by building age.
NYC’s source water is among the cleanest of any major US city for PFAS, but lead from building plumbing is a real concern in pre-1961 properties. About 250 public systems statewide exceed the state’s own 10 ppt PFAS standard. The December 2025 DEC rural soil study found near-universal PFAS presence in soils statewide. Private well owners — approximately 1 million in New York — should test for PFAS and other contaminants. Residents can check our water quality checker and request their utility’s Consumer Confidence Report for local detail.
What are PFAS chemicals and why are they a concern in New York?
PFAS (per- and polyfluoroalkyl substances) are synthetic “forever chemicals” that don’t break down naturally in the environment or the human body.
In December 2025, DEC confirmed PFOS is present in more than 97% of rural soil samples statewide — making clear that contamination extends far beyond known industrial sites. About 250 New York water systems exceed the state’s own 10 ppt standard for PFOA and PFOS, and approximately 189 systems have detections between 4–10 ppt that will require action under federal rules by 2031. New York was among the first states to set enforceable PFAS MCLs in 2020 and is expanding product bans and wastewater treatment plant monitoring in 2026. See our filter guide for NSF-certified PFAS removal options.

• Private Well Testing: Private well owners can contact local health departments for testing guidance; those in eligible counties can apply for the state’s 2026 free PFAS pilot programme
Why does New York have water infrastructure challenges?
New York’s water infrastructure faces several interconnected challenges in 2026:
Aging Pipes: Many systems were built decades ago; some distribution pipes are over 100 years old. More than 1.25 million service lines statewide are lead or possibly lead, with replacement estimated at $695 million per year over the next decade
Funding Gaps: The state faces a $44.2 billion need for drinking water infrastructure over 20 years. Despite record investment — $6 billion since 2017, with $3.75 billion more proposed — the gap remains significant
PFAS Everywhere: The December 2025 rural soil study confirmed near-universal PFAS presence statewide, expanding the scope of contamination well beyond industrial zones and requiring broader regulatory response
Access Barriers: Small and rural communities struggle to navigate complex grant processes; as of August 2025, 140 public water systems had still not submitted required lead pipe inventory data

Contaminants of Concern
PFAS “Forever Chemicals”
Source: Industrial manufacturing, firefighting foam at airports and military installations, consumer products including non-stick cookware and stain-resistant textiles, landfill leachate, and wastewater treatment plant discharges. A December 2025 DEC statewide rural soil study found PFOS present in more than 97% of surface soil samples — confirming contamination is effectively statewide
Health Effects: Linked to kidney and testicular cancer, liver damage, immune system suppression, high cholesterol, thyroid disease, and developmental effects in children
Current Status (2026): Approximately 250 New York water systems exceed the state’s own 10 ppt standard; around 189 systems with detections between 4–10 ppt will require action under federal rules by 2031. A 2026 private well pilot programme offers free PFAS testing and up to $10,000 in rebates for residents in six counties. New product bans on carpets, menstrual products, and eventually all consumer goods are rolling out through 2032. EPA Limits: 4 ppt for PFOA and PFOS individually. See our filter guide for certified PFAS removal options.
Lead Service Lines
Source: Legacy lead pipes and service lines installed before 1986, particularly in older urban areas and buildings. Lead does not come from New York’s source water but leaches into water as it passes through pipes and fixtures in older properties
Health Effects: Neurological damage, developmental delays in children, cardiovascular effects, kidney damage, and cognitive impairment. There is no safe level of lead exposure, particularly for children
Current Status (2026): More than 1.25 million New York service lines are lead or possibly lead — over one in three statewide — potentially affecting 3.1 million residents. NYC alone has 123,000 pipes requiring replacement. On Long Island, 90%+ of Nassau County’s lead pipes are concentrated in just eight water districts. Governor Hochul announced $66 million specifically for lead service line replacement. Federal rules now mandate replacement of all lead lines within 10 years of 2027. Action Level: 15 ppb in tap water triggers treatment requirements; NY schools must act at 5 µg/L. If your building was built before 1961, consider a certified lead filter — see our water filter solutions guide.
